Proposal for constraining non-Newtonian gravity at nm range via criticality enhanced measurement of resonance frequency shift
Lei Chen, Jian Liu, Ka-di Zhu
We propose a quantum mechanical method of constraining non-Newtonian gravity at the nanometer range. In this method, a hybrid electro-optomechanical system is employed. Applying a…
Proposal for measuring Newtonian constant of gravitation at an exceptional point in an optomechanical system
Lei Chen, Jian Liu, Ka-di Zhu
We develop a quantum mechanical method of measuring the Newtonian constant of gravitation, G. In this method, an optomechanical system consisting of two cavities and two membrane r…
Constraining Axion-to-Nucleon interaction via ultranarrow linewidth in the Casimir-less regime
Lei Chen, Jian Liu, Kadi Zhu
In this paper we develop a quantum optical method to detect the axion-nucleon interaction. We ultilize a levitated optomechanical system consisting of a silica nanosphere and an op…
Gravitational waves detection with exceptional points in micro cavities
Jian Liu, Lei Chen, Fei He +1
Here we propose a new gravitational waves(GWs) detector in broad frequency band, which is operated at exceptional points(EPs) in micro cavities. The detected signal is an eigenfreq…
Enhanced sensing of non-Newtonian effects at ultrashort range with exceptional points in optomechanical systems
Jian Liu, Lei Chen, Ka-Di Zhu
We propose an optomechanical nano-gravimeter based on exceptional points. The system is a coupled cavity optomechanical system, in which the gain and loss are applied by driving th…
Ultrasensitive optomechanical detection of an axion-mediated force based on a sharp peak emerging in probe absorption spectrum
Lei Chen, Jian Liu, Kadi Zhu
Axion remains the most convincing solution to the strong-CP problem and a well-motivated dark matter candidate, causing the search for axions and axion-like particles(ALPs) to attr…
